POLE.

Specification of Letters Patent.

Patented J illy 27, 1920.

Application filed September 7, 1918. Serial No. 253,116.

To all lwhom it may concern.' Y

Be it Yknown that I, JAMES EDWIN SMITH, a citizen of the United States, residing at Pueblo, in the county of .Pueblo and State of Colorado, have invented certain new and useful Improvements in Poles, of which the following is a specication.

This invention relates to metallic building structures, and more especially to poles adapted for supporting wires and the like; and the object of the same is to construct an improved skeleton structure pole entirely of channel iron, angle iron, and strip iron, for supporting telegraph and telephone wires, and possibly for other uses which may not be enumerated here.

An important feature of the invention is. the details of structure at the ground line where the body of the pole joins the base thereof.

Other features are set forth in detail in the following specification and claim, and attention is drawn to the drawings where- 1n:- Y

Figure 1 is an elevation of this pole set up, being a section through the concrete in which its base is set. p

Fig. 2 is a plan view of the pole with one cross arm shown at right angles to another.

Fig. 3 is an enlarged horizontal section on the line 3--3 of Fig. l.

The body of the pole is as tall as may be required. It is made up of two channel iron members 1 and 2 whose flanges may project outward although they are shown in Fig. 3 as projecting inward toward each other, and a series of short straps of striplike members connecting these channel iron side pieces. On the front side of the pole the strips may be riveted to the flanges about twelve inches apart, center to center so as to constitute steps 3, the rivets or bolts l passing through the steps and through the flanges V5 as shown; and on the rear side of the pole the strips 6 may be used as often as necessary consistent with the height of the pole, and are riveted or bolted to the rear flanges in the same manner.

The base is made up of two channel iron members 11 and 12 whose flanges 15 are shown in Fig. 3 as turned outward, and these members are spaced so that the lower ends of the body members 1 and 2 may pass between them; and the base is completed by front and rear strips 13 bolted or riveted to its anges as at 14, the strips 16 at the lower end of the vbase being somewhat wider and the whole base being embedded in the earth and preferably in cement as indicated by the letter C. At the groundv line indicated at Gr, two angle iron elements 17 are employed, preferably somewhat longer than the vstrips 13, their upright flanges being riveted as at 18 and 19 to the flanges of the base and the body members, and their lower or horizontal lianges preferably resting on the ground. I abstain from giving dimensions of parts, but by preference the channeled members will be of about the same width as the strips which connect them so that the structure will be square. In this case the angle iron elements 17 will be somewhat longer so that they project at their eX- tremities beyond the otherwise square structure as seen in Fig. 3, and afford a considerable brace for the same because they lie on the ground. If this pole should be erected on a street where the surface of the ground is paved, these elements 17 might lie upon the paving or perhaps be embedded a little in it, but I consider it essential that they bei longer than the structure is wide on any si e.

.The cross arms are also angle iron elements. In Fig. 1 I have shown two arms 20 and 21, whose upright lianges are bolted or riveted as at 22 to the anges 5 of the side members 1 and 2, and in Fig. 2 I have shown how the horizontal ianges of these arms may be pierced with openings 23 so that insulators may be passed through and mounted in the same. In Fig..2 I have shown also another arm 24 at right angles to those mentioned, in which case it would lie alongside one of the members 1 and 2 and be bolted or riveted thereto by means not necessary to amplify. In Fig. 1 I have shown small holes 25 in the upright flanges of these arms, through which U-bolts or other forms of bolts may be passed for clamping in the insulator pegs against the arms, if the pegs are not of the proper size to engage the yopenings 23. The metal of which this structure is made should be properly treated to preserve it from weather and other iniuences which would tend to destroy it.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts,

Vmaterials, dimensions, et cetera, asv may what I claim as new and desire to secure by a A pole comprising' a pair of parallel vertically extending channel iron members, cross strips connecting the members intermediate their ends, a base comprising parallel vertically extending channel iron mem bers, said members being so spaced as to receive the lower ends of the first mentioned channel iron members therebetween, cross strips Connecting the channel iron members of the base, and stripsse'cured to the lower ends of the first mentioned channel iron members and upper ends of the baseV channel iron members, said strips extending transversely of said channel ironv members and beyond the outer Vfaces thereof.

In testimony Wliereorl I affix my signature in presence of two Witnesses.
